Thanks weldmonger for the excellent video on 2T/4T. I've been told that in Europe, many tig welders use torch switches exclusively rather than foot pedals and use the 4T technique to "bracket" the ideal welding amperage. While I can understand this, I still prefer the foot pedal. However, I can also see where the switch/4T setup would be useful for out of position work where it's not practical to use the foot pedal and/or the ideal welding current cannot be set on the machine ahead of time because of different current requirements required by position changes or heating of the base metal. How to you view this?

Jody doesn’t monitor or participate in this forum, so any direct questions to him won’t be answered by him. You might post your question to him in the video you watched since he does reply to those. Make sure the video is recent though since he has a library of thousands on his channel and he is most unlikely to reply to a video from weeks, let alone years ago.

Some welders can't weld without a pedal, without 6010 electrodes and without C25 but, except for procedures, they are choices, not requirements.
You can try to force the situation to comply with your preference, or you can be flexible and get the job done.

I guess I should have been more specific. I was just wondering if anyone used this technique in their tig welding and how it worked out for them.

i have the feature on one of the welders but never tried it. tho the torch buttons are horrible to use. i have the amp +/- buttons on the torch but they are so hard to press that the torch rocks and so tiny for my big fingers.

I don't use the current control buttons/pot on the torch because I tend to lose control of the arc as tweake said. Some machines give 4T type current control using 2T - I've used that on occasion.

I have several machines that have 2T and 4T. I also have "sliders" for mounting to the torches. My hands are so messed up from being broken that I find that I have to use 4T and a slider combo to control the heat because my fingers don't work so fast to set the 4T which will go to max, find out that is too much to run the entire weld, jumping from full to off and back again. I also have a tig button that acts like a foot pedal right on the torch. That does take getting used to, but functional. Every one has different likes and dislikes.
